SLIDE-BEST.

Application filed January 10, 1912. I Serial No. 670,396.

T 0 all whom it may concern Be it known that I, GUsTAvE R. KAos- MARIE,a subject of the King of Hungary, and a resident of the city of NewYork, borough of Manhattan, in the county and. State of New York, haveinvented a new and Improved Slide-Rest, of which the following is afull, clear, and exact description.

The invention relates to lathes used by jewelers and other persons, andits object is to provide a new and improved tool slide rest arranged topermit universal adjustment of the tool relative to the work.

For the purpose mentioned use is made of a spindle mounted to turn inthe tool post and provided with a horizontally-disposed guideway onwhich is mounted to slide a head for carrying the tool, the said headbeing engaged by a screw rod journaled on the guideway. Use is also madeof a tooladjusting screw rod screwing in the head and arranged parallelto the tool, the said tool-adjusting screw rod being provided with acollar engaging a recess in the tool for shifting the latter in thedirection of its length on screwing the said tool-adjusting screw rodinward or outward in the head.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a perspective view of the slide rest in position on thelathe; Fig. 2 is a plan View of the tool holder; and Fig. 3 is atransverse section of the same on the line 3-3 of Fig. 2.

The tool post A is pivotally connected at the front of its base A by apivot B with a support G adjustably attached to the bed D of the lathe,the saidbase A being normally locked in place on the support 0 by ascrew E screwing in the support C and having its head extending over thetop of the base A. A portion of the head of the screw E is cut off sothat when the screw E is turned to bring its flat face into a forwardposition then the base A is unlocked and the tool post can be swung overand with it the parts supported thereby, to permit of swinging the toolpost and parts carried thereby out of the way whenever it is desired touse the lathe without the tool cally-disposed split socket or bearing Ain which is mounted to turn a spindle F adapted to be fastened in placein the bearing A by clamping split portions in firm contact with thespindle F, the portions being engaged by a handled screw G to open orclose the split sections.

On the upper end of the spindle F is secured a horizontally-disposedguideway H on which is mounted to slide a head I provided with anopening I at right angles to the guideway H and adapted to receive thetool J fastened in place in the head I by a handled screw K, as plainlyindicated in Fig. 3. In the head journaled in lugs I extending upwardlyat the ends of the guideway H, and on one end of the screw rod L issecured a handle L under the control of the operator for turning thehead I and with it the tool J lengthwise of the guideway H.

In order to shift the tool J in the head I after the tool is unlocked bythe screw K, use is made of a screw rod N arranged parallel to the toolJ and screwing in the head I. The outer end of the screw rod N isprovided with a handle N under the control of the operator for turningthe screw rod N, and on the latter is secured or formed a collar Nengaging a recess J formed in the rear end of the tool J. Thus when thescrew rod N is screwed inward or outward in the head I a correspondingsliding movement is given to the tool J as the latter is carried alongby the collar l 2 engaging the recess J.

From the foregoing it will be seen that by the arrangement described thespindle F can be readily turned in the bearing A of the tool post, thehead I carrying the tool J can be adjusted lengthwise on the guideway IIand the tool J can be adjusted transversely in the head I by the screwrod N. Thus by the arrangement described, the operator is enabled toreadily bring the cutting end of the tool into the desired positionrelative to the work, the tool J may be fed inward on turnin the handleN, and the tool J can be bodily fed on the operator turning the handleL.

It is understood that in slide rests as now I screws a screw rod L Thetool post A is provided with a vertiv j screw rod L with a'view to shiftthe Having thus described my invention, I claim as new and desire tosecure by Letters Patent:

1. A slide rest for the tool posts of lathes,

comprising a spindle mounted to turn in the tool post, a horizontalguideway attached to the upper end of the said spindle, a head mountedto slide on the said guideway and adapted to carry the tool, ahead-adjusting screw rod journaled on the said guideway and screwing inthe said head for adjusting the latter on the guideway, and a secondscrew rod screwing in the said head and arranged at a right anglerelative to the said L 'uideway, the said second screw rod having meansfor engagement with the tool to slide the latter in the direction of itslength.

2. A slide rest comprising a tool post, a

' base on which the said tool post is mounted to swing in a verticalplane, means for fas tening thetool post to the base, a vertical spindlemounted to turn in the said tool post, a guideway fixed on the upper endof the said spindle and provided at its ends 0 with upturned lugs, atool-carrying head mounted to slide on the said guideway, and a screwrod journaled on the said lugs and screwing in the said head.

3. A slide rest, comprising a tool post, a

base on which the said tool post is mounted to swing, means forfastening the tool post to the base, a vertical spindle mounted to turnin the said tool post, a guideway fixed on the upper end of the saidspindle and provided at its ends with upturned lugs, a tool-carryinghead mounted to slide on the said guideway and provided with an openingfor the tool, the said opening extending at a right angle relative tothe said guide- ,way and screw rod, and a second screw rod screwing inthe said head and arranged parallel to the said opening, the said secondscrew rod having a collar adapted to engage a recess in the tool. 7

4:.
